One firearm is enough for me and my limited hide pockets and such...... I must admit I am in and out of a vehicle a lot of times in a 8-10 hour working day..... I have yet to find a comfortable 100% of the time compact and hoster or carry device. I know if I was an active LEO my answer would likely be different........ Just me......To each his own and if you can do it and be comfortable go for it.... what could it hurt....?
